'RECORD-CARD FOR SCALES.

SPECIFICATION forming part of Letters Patent No. 642,757, dated February 6, 1900.

Application filed April '7, 1898.

To all whom it may concern:

Be it known that I, MATTHEW H. REED, a citizen of the United States of America, and a resident of Allegheny, countyof Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Record- Gards for Scales, of which the following is a specification.

Figure I shows my improved record-card arranged for use on railroad-scales. Fig. II shows the card made duplex for recording both gross and tare weight, and Fig. III shows the card arranged for use on scales provided with a counterpoise.

My invention, generally stated, relates to a record-card provided with graduations for scales, the particular character of which is more specifically set out below.

The following is a detailed description of my invention. I divide the card A, portion B, Fig. I, by vertical and horizontal grad nations, each vertical graduation denoting a predetermined unit, as twenty thousands, as in Fig. I, and each horizontal graduation denoting some other predetermined unit, as thousands, the unit of increase denoted by the vertical graduations being a multiple of the unit of increase denoted by the horizontal graduations. In Fig. I, I have shown in portion B the graduations indicated by lines, the vertical lines marking the horizontal graduations and the horizontal lines marking the vertical graduations. The graduations progress from left to right for the thousands and from bottom to top for the twenty-thousands. Accordingly the sum of five thousand would be indicated by punching or marking the foot of the fifth vertical line to the right of the first or zero vertical line, while the sum of twenty thousand wouldbe indicated likewise at the left-hand extremity of the second horizontal line, counting from bottom to top. It will be readily seen that the sum of these two amounts-viz, twenty-five thousandwould be indicated by the intersection of these two lines. For convenience the number of thousands indicated by the intersections of the horizontal and vertical lines is shown by numerals placed above and to the right of such intersections.

In railway-sca1es the portion B of the card A above described will record the reading on Serial No. 676,744:- (No model.)

the main beams, while the readings on the secondary beam will be recorded on portion 0 of card A, graduated horizontally to tens of pounds up to a thousand to correspond to the graduation on said secondary beam. The amount of the weight would be indicated on portion 0 by punching or marking the graduation on said portion corresponding to the position of the poise on said secondary beam when the scale is balanced with the load. Thus if the weight indicated on the secondary beam be six hundred and fifty pounds the line punched or marked would be the sixty-fifth line on portion 0 to the left of the zero-line. The total weight on the whole card would then be the sum of twenty-five thousand and six hundred and fifty, being the entire weight indicated on both beams.

Fig. II shows a card made duplex for recording both the gross and tare weight. The upper portion D of the card is graduated in reverse of the lower portion E, since the card would be reversed when portion Dis inserted in the punching or marking device on the scale. Otherwise the graduations and fig ures are the same as in Fig. I. In using this card the gross weight of the loaded car is first obtained and portion D of the'card A inverted and inserted in the punching or marking mechanism and the amount of the weight registered thereon. Then the car after being unloaded is again run on the scale and weighed, and the weight is indicated on portion E of card A by means of the punching or marking device. The amounts of gross and tare weight are entered in the blanks provided therefor on the card, and their diiference is the weight of the load.

The form of card A shown in Fig. III is for use with a scale provided with a counterpoise. The amounts over a thousand indicated by the counterpoise are registered on portion F of card A Portion F is graduated horizontally and vertically, the horizontal graduations denoting a predetermined unit of increase-say a thousandwhile the vertical graduations denote a second predetermined nnit of increase, being a multiple of said first unit-say twenty thousand. The lower portion G of said card A is graduated likewise vertically and horizontally, the vertical graduations denoting a predetermined unit of increase-for instance, as in Fig. III, twohundred-while the horizontal would then indicate some unit of which said first unit is a multiple-as in Fig. III, two and a half. The portion G is intended to receive the readings on the beam. the amounts on portions F and G in Fig. III is the same as described in connection with portion B, Fig. I, and the sum of the readings on portions F and G would be the total Weight shown on the scales.

The horizontal and vertical lines are not essential to my invention, as instead of the lines and the intersections of said lines I may substitute the numbers they represent, and the mark or puncture would be received in said numerals. Again, I may use both the line and the numerals, marking or punching on the numerals.

By means of this form of card I provide an expeditious method of indicating weights and a convenient and ready means for their preservation and reference.

The merits of my invention consist especially in the ease and despatch with which a record of weightsindicated on registering and recording scales may be obtained and read, and these cards may be filed away conveniently for future reference, occupying a minimum space.

What I wish to claim is 1. A record-card for scales having one portion graduated for the main beam horizon- The method of indicating crease indicated by the progressive horizontal graduations, and another portion graduated progressively for the secondary beam.

2. A record-card for scales having two divisions, the first division having one portion for the main beam graduated horizontally and vertically, the unit of increase indicated by the progressive vertical graduations being the multiple of the unit of increase indicated by the progressive horizontal graduations, said division having another portion also havin g a progressive graduation for the secondary beam, the whole being intended to indicate the gross weight and a second division on said card graduated like the first so far as specified above except reversely to indicate the tare weight.

3. A record-card forscales having one portion graduated both horizontally and vertically, and the other portion graduated progressively in a horizontal direction, both sets of graduations indicating weights, substan tially as described.

4. A record-card for scales having one portion graduated horizontally and vertically, to indicate the amount from the main beam, and another portion graduated progressively in a horizontal direction to indicate the amount from the secondary beam, substantially as described.

Signed by me at Pittsburg, Pennsylvania, this 2d day of April, 1898.
